The Science

Ashwagandha (Withania somnifera) modulates the hypothalamic-pituitary-adrenal (HPA) axis, lowering stress hormones and reducing sympathetic overdrive. It’s been shown to:
Lower anxiety scores on validated mood scales
Reduce serum cortisol in adults under chronic stress
Improve muscle recovery and VO2 max
Increase testosterone and DHEA-S in male participants
Improve sleep latency and sleep quality in insomnia patients
Dosed at 500mg/day, it offers broad-spectrum support for mental, metabolic, and hormonal health, with minimal side effects.

How will I know its working?

Ashwagandha is one of the most well-studied adaptogens in functional medicine — known for its ability to lower cortisol, improve resistance to stress, and support mood, energy and hormonal balance.

When to take it?

Take 1 capsule daily with food and water, unless specified otherwise on the sachet.
